-
Double-click the tNeo4jInput component to
open its Basic settings view.
-
Select the Use an existing connection
check box to reuse the connection opened by the tNeo4jConnection component. -
Click the […] button next to Edit schema and define the schema corresponding
to the node properties you want to retrieve and display. In this example,
the schema is composed of two columns, name and position, both
of type String.When done, click OK to close the
[Schema] dialog box and propagate the
schema to the next component.
The defined schema columns automatically appear in the Mapping table. -
In the Query field, type in the Cypher
query to match the data to read from the Neo4j database. In this example,
use the following Cypher query to find the name and position of the manager
whose ID is 2.1"MATCH (ee:Managers{id:2}) RETURN ee.name, ee.position;"or1"MATCH (ee:Managers) WHERE ee.id = 2 RETURN ee.name, ee.position;" -
Fill the Return parameter field for each
schema column with a return parameter in double quotes to map the node
properties in the Neo4j database with the schema columns. -
Double-click the tLogRow component to
open its Basic settings view, and select
the Table (print values in cells of a
table) option to display the retrieved information in a
table.
